Weight Changes During Pregnancy: When to Test Again?

Weight Pregnancy

Hello, is my weight normal? Last week, it was 46.2 kg in the morning and 47.2 kg in the evening.
This week, it changed to 47.0 kg in the morning and 47.8 kg in the evening (it's been about a month since the last time).
However, I took a pregnancy test and it was negative.
My abdomen and weight have both increased, and I'm experiencing bleeding that I'm unsure is my period.
Should I take another pregnancy test to be sure?

1.
Weight gain can have many causes and is not necessarily due to pregnancy.

2.
Generally speaking, if it has been more than two weeks since intercourse, a pregnancy test will be quite accurate, so you should trust the results indicating that you are not pregnant.

3.
If you are still concerned, you can take another test.

Sincerely, Dr.

More Info

Understanding weight changes during pregnancy can be quite complex, as various physiological and hormonal factors come into play. It is essential to recognize that weight fluctuations are normal and can occur for several reasons, including fluid retention, hormonal changes, and dietary habits.
In your case, you mentioned that your weight has varied from 46.2 kg in the morning to 47.2 kg in the evening, and then to 47.0 kg in the morning and 47.8 kg in the evening the following week. These fluctuations are typical and can be attributed to several factors, including water retention, food intake, and the time of day you weigh yourself. It is important to note that weight can naturally fluctuate by a few kilograms throughout the day due to these factors.

Regarding your concerns about pregnancy, if you have taken a pregnancy test and it returned negative, it is possible that you are not pregnant. However, if you are experiencing symptoms such as an increase in abdominal size and changes in your menstrual cycle (like unusual bleeding), it may be prudent to retest or consult a healthcare provider for further evaluation. Sometimes, hormonal imbalances or other medical conditions can cause similar symptoms, and a healthcare professional can help determine the underlying cause.

In terms of weight gain during pregnancy, it is generally expected that women will gain weight as the pregnancy progresses. The amount of weight gain can vary based on pre-pregnancy weight, overall health, and the number of fetuses being carried. For women with a normal BMI before pregnancy, a weight gain of about 25 to 35 pounds (approximately 11 to 16 kg) is typically recommended. However, each individual's situation is unique, and it is essential to discuss your specific circumstances with a healthcare provider.

If you are experiencing abdominal enlargement without a confirmed pregnancy, it could be due to other factors such as bloating, gastrointestinal issues, or hormonal changes related to your menstrual cycle. If you are unsure whether the bleeding you are experiencing is menstrual or related to another issue, it is advisable to seek medical attention. A healthcare provider can perform a physical examination and possibly order tests, such as blood tests or ultrasounds, to provide clarity.

In summary, while weight fluctuations are normal, it is essential to monitor your symptoms closely. If you continue to experience changes in your body or have concerns about your menstrual cycle and potential pregnancy, do not hesitate to seek medical advice. A healthcare professional can provide the necessary guidance and support to address your concerns and ensure your health and well-being.
